SHUTTER-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 407,308, dated July 16, 1889.

' Application iiled November 29,1887. Serial No. 256,37 9. (Model.)

T0 all whom, t may concern:

Be it known that I, AVERY VAN IVIE1 a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented an Improvement in Shutter-Fasteners, of which the following is a specification.

My invention relates to improvements in shutter-fasteners, the objects being to provide a fastener which shall be durable, simple, efficient, and cheap; and with these ends in view my invent-ion consists of certain details in construction and combinations of parts, as will be more fully pointed out and explained in the following specification and claim.

In the accompanying drawings, Figure 1 is a front view of my device. Fig. 2 is a view, looking edgewise, ot the bar when the latter is in a locked position. Fig. 3 is a sectional view ot Fig. 1 on line y, looking in the direction of arrow. Figs. 4 and 5 are detail plan and sectional views of recessed side of locking-bar.

h is the housing or casing, in the center of which is pivoted locking-bar b, for which purpose the latter is provided with hole a.

k is the keeper of the lock.

The broken lines c representthe position of the locking-bar when it is disengaged from the keeper, or in an unlocked position.

At r is seen an annular depression, the surrounding Walls of which have vrecesses at r and r2 adapted to receive the spring s alternately as the bar 'is moved to or from engagement with the keeper. The spring s is held in the base of housing bearing on points p, and extending through aperture between these two points and through housing, proj eeting outside sufiiciently that it Inay be easily depressed by a pressure given on this external end by the thumb or Iinger when desired and the spring brought to the position shown by broken lines s', when the spring is entirely clear of the bar that it (the bar) may be moved to either position desired, and releasing the spring, it will enter one of the two recesses, r and r2, and will retain the bar in a relative position. Thus the said recesses being located at right angles to each other, when the bar is in the position shown by dotted lines c the recess r2 will fall directly over the spring, and when the bar is in the position seen at b, Fig. 1, the recess fr will fall directly over spring, so that the bar is held securely either in a locked or unlocked position. to catch hold of with the -thumb or iinger to draw the bar from the keeper on unlocking.

In use the fastener is placed in the ordinary manner, the housing 71. on one and the keeper k on the other of a pair of shutters, either in the position shown at Fig. 1 or reversed, so that the bar will extend downwardly on being unlocked.

It is evident that slight changes might be made in the construction of my device without departing from the spirit and scope of the same; hence I desire to have it understood that I feel at libertyy to make any such changes as fall fairly within such scope.

Having fully described my invention,what

ent, is

In a shutter-fastener, a housing h, adapted at p to receive the fixed end of spring s,abar

o, pivoted at a within said housing, said bar AVERY VAN VIE.
